Select the downloaded file webc-VERSION.iso (you need to change the file filter to *.*) and target device, and click
"Write" (Note: this will wipe all information you have on the selected USB stick.
So be very careful to note the correct drive letter assigned to your USB stick
at step.4)

Remove your USB stick when the operation is complete

If you re-insert the USB key once specially formatted with Webconverger,
Windows may ask if it should format the USB stick. Ignore this, it's because
Windows doesn't understand the filesystem now on your USB stick.
